What is a crane trolley?
The crane trolley is an important part of the lifting machinery and is mainly used to support and move the main structure of the crane. It usually consists of wheels, frames, driving devices, braking systems and other components. It can run smoothly on the track or the ground and realize the horizontal movement of the crane. The design and performance of the crane trolley directly affect the stability, load-bearing capacity and work efficiency of the crane.
With the continuous development of industrial technology, the application scope of crane trolleys is becoming more and more extensive, covering many fields such as construction, ports, metallurgy, and logistics. The following will introduce the relevant knowledge and application scenarios of crane trolleys in detail based on the hot topics and hot content on the entire network in the past 10 days.
1. Main types of crane trolleys
According to different structures and functions, crane trolleys can be divided into the following types:
| Type | Features | Applicable scenarios |
|---|---|---|
| Orbital trolley | Relying on rail operation, it has high stability and strong carrying capacity. | Large factories, ports and terminals |
| tire trolley | High flexibility, no need for tracks, easy to move | Construction sites, logistics and warehousing |
| Crawler trolley | Large grounding area, suitable for soft ground | Mining and field operations |
2. Core components of crane trolley
The performance of a crane trolley depends on the design and manufacturing level of its core components. The following are the main components of the trolley and their functions:
| parts | Function | Common materials |
|---|---|---|
